Translate Toolkit

The Translate Toolkit is an essential toolkit for localization engineers. It contains tools and documentation to help localizers convert, count, manipulate, review and debug localization files with less repetitive work.

The software includes programs to convert localization formats to the common PO and XLIFF formats. There are also programs to check and manage PO and XLIFF files. The Toolkit is part of the Translate project, hosted at <https://github.com/translate/translate>.

At its core the software contains Python classes for handling localization storage formats such as DTD, properties, OpenOffice.org GSI/SDF, CSV, MO, Qt .ts, TMX, TBX, WordFast txt, Gettext .mo, Windows RC, PO and XLIFF. It also provides scripts to convert between these formats.

Maintained by Weblate — a privacy-respecting localization platform built on open-source foundations.

Features

• Format converters for localization, translation and software formats, so translators can work in standard translation formats.

• Quality assurance tools for pattern searches, language-aware checks, terminology extraction and other review tasks.

• Python APIs that can be expanded with new formats, project types, localization tests and language modules.

Project goals

The vision of the Translate Project is to be a meta project for localizers built on the premise that your language deserves to be a project on its own right not a poor cousin of the main project.

Most projects are inattentive to the needs and difficulties experienced by localizers. To that end the aim is to work towards creating tools and documentation that allows localizers to focus on what they do best: translating software.

Requirements

The recommended installation is using uv or pip in a virtual environment:

uv pip install translate-toolkit

or:

pip install translate-toolkit

You can also download a stable released version from <https://github.com/translate/translate/releases> and install it manually.

The Toolkit requires Python 3.11 or newer. The required runtime dependencies are lxml>=6.1.0,<7.0 and unicode-segmentation-rs>=0.2.0,<0.3.

There are several optional dependencies for format-specific features and speed ups. They can be requested as extras during installation:

# Install all optional dependencies
pip install translate-toolkit[all]

# Install selected optional dependencies
pip install translate-toolkit[markdown,ini,ical,subtitles,yaml,spellcheck]

Available extras include chardet, fluent, ical, ini, levenshtein, markdown, php, rc, spellcheck, subtitles, toml and yaml. Please check pyproject.toml for the current dependency versions.
